A first-order reaction is taking place inside a porous catalyst. Assume dilute concentrations and neglect any variations in the axial (x) direction.

(a) Derive an equation for both the internal and overall effectiveness factors for the rectangular porous slab shown in Figure 7.

(b) Repeat part (a) for a cylindrical catalyst pellet where the reactants diffuse inward in the radial direction.
